Abstract

Outgoing phone calls can be made on a handheld electronic device that has been locked to prevent unauthorized use through an override that permits the making of outgoing phone calls while applications additional to the phone application remain locked. In some embodiments, the override can not be selected unless first enabled by a remotely generated enable override authorization signal.

Claims

1. A handheld electronic device comprising:

a user interface;

a phone application for making outgoing and receiving incoming phone calls using the user interface;

at least one additional application implemented through the user interface;

a lockout enableable to be activated and deactivated and, when activated, structured to restrict use of the phone application and not allow use of all of the additional applications where the restricted use comprises allowing the receipt of incoming phone calls, and wherein the lockout is structured to be deactivated by receipt of a security code at the user interface; and

an override enableable to be selected and deselected, and, when selected while the lockout is activated, structured to allow the making of outgoing phone calls by the phone application that are otherwise disallowed by the activated lockout, while maintaining the activated lockout of the additional applications; and

where the override may be changed by receiving input at the user interface if the handheld has received an override authorization signal from a remote supervisory station and if the lockout is deactivated.

2. The handheld electronic device of claim 1 wherein the phone application further comprises a hot list from which outgoing phone calls can be made with the lockout activated and the override selected.

3. The handheld electronic device of claim 2 wherein the hot list is selected from a group consisting of:

a list of frequently called phone numbers,

a list of most recently called phone numbers,

an alphabetical list of most frequently called phone numbers, and

a call log list.

4. The handheld electronic device of claim 1 wherein the user interface comprises a keyboard having keys and the phone application further comprises a speed dial option by which selected keys are programmed to initiate the outgoing phone calls to selected phone numbers when actuated, the speed dial option being usable when the lockout is activated and the override is selected.

5. The handheld device of claim 1 wherein the lockout is enabled to be deactivated by receipt of a security code at the user interface.

6. The handheld electronic device of claim 1 wherein the lockout is activated when the user interface does not receive input for a predetermined period of time.

7. The handheld electronic device of claim 1 wherein the user interface comprise a keyboard having keys that are sequentially actuated to dial a selected phone number when the lockout is activated and the override is selected.

8. A method of enabling operation of a handheld electronic device having a phone application and additional applications, the method comprising:

activating a lockout structured to restrict the making of outgoing phone calls by the phone application while allowing receipt of incoming phone calls and simultaneously disallow use of the additional applications, and structured to be deactivated by detecting input of a security code at a user interface;

enabling use of an override, the override structured to be selected and deselected and, when selected, to maintain the lockout of the additional applications while allowing outgoing phone calls that are otherwise disallowed by the activated lockout by the phone application;

said override enabled by receipt of an enable override authorization signal received from a remote supervisory station, and settable to be selected only when the lockout is deactivated.

9. The method of claim 8 further comprising changing a current setting of the override while the lockout is activated by detecting receipt of a security code at the user interface;

deactivating the lockout, and, detecting selection of a change to the current setting of the override.

10. The method of claim 8 wherein enabling the an outgoing phone call while the additional applications remain locked out comprises displaying a hot list from which the outgoing phone call can be made.

11. The method of claim 10 wherein the hot list is selected from a group comprising:

a list of most recent phone numbers called,

a list of most frequent phone numbers called, an alphabetical list of most frequently used phone numbers and a call list.

12. The method of claim 10 wherein displaying the hot list comprises displaying the hot list on a display screen with an indicia that the handheld electronic device is in security override mode.

13. The method of claim 8 wherein enabling the user to make an outgoing phone call while the additional applications are locked out comprises providing a number of keys, enabling programming at least one of the number of keys with a selected phone number, and enabling dialing the selected phone number when the at least one of the number of keys is actuated.
